For those of you planning a cooling/fan/enclosure system - BitFury reports that the chips have an optimal operating temperature range of 45C - 50C measured on the package. Cool them too much and they actually don't perform as well.

Do you think we need an enclosure of some kind for heat management or will we get by just fine without one? I was planning on just sitting a fan next to it, should it be needed.

This is all Tytus is doing and its working fine, but yes you will want a bit of air movement.

If you clock it up a bit in software, you'll definitely need fans...

Wha?! I let something slip?!

if anyone know who own bitfury 2147483 Mhash/s mining on Slush pool.

If I had to guess, it is someone trollin'

Please leave BF boat alone and go back to your Avalon boat please.

I'm already on both boats, and I don't jump ship unless it's on fire. I've done and jumped from BFL's ship long ago. Cheesy

Stick the test unit in one of these so we can see what it looks like...

Wow thats kind of dissapointing, I was hoping to chuck them outside for the winter. Does the default hardware and/or software allow any overclocking to compensate ?

Keep in mind that putting them out in -5C weather doesn't make the chips run at -5C. They're still generating heat...

Yes, that was the very first prototype board, only a very few
were made. Later H-CARDs have mounting holes.

In fact, only the very first two cards were ordered without mounting holes.

Thanks for the clarification.

For those of you planning heatsinks, Intron provides a good reference.

PS: You are looking thru the board from the top side.
Don't make the 'mirror error' too often made:) --Intron

Hi Dave,
I know this is an old post, but just needed to confirm something: the image at the link you included above shows 6 mounting holes on the PCB whereas the PCB in the picture in this link https://bitcointalksearch.org/topic/m.2676985 seems to have none.

Which is accurate? I assume that the photograph is of a prototype PCB which predated the mounting holes, but I'd like to know for sure. Thanks.

I believe the default hardware is limited by a 30A regulator (or some electrical engineering thingamajig). There is quite a discussion about it when c-scape demonstrated their S-Hash card (which has the higher power capacity). If you search in the forum (and this thread), you will find more info about it.
Here is one link:
https://bitcointalk.org/index.php?topic=251966.msg2797461;topicseen#msg2797461

tl;dr: Boards designed for stable environment of 100TH mine. No overclocking without extensive manual reflowing the components on the boards (200+ per board?)

I ordered a 400 GH/s Kit. only the October delivery was available. I want to pay via credit card but it is unclear what I am supposed to do as it says it is manual processing and there was no choice for credit card when ordering.

click pay by bank then put note pay by CC

Thanks for the updates Dave. Are you still planing to hold off on hosting plans until Nov?

Yes. I'm trying to get to the point where I can offer individual hosted units, but at this time its looking like I might need to keep the offer at half-rack hosted (8 full rigs) and full rack hosted (16 rigs). The ability to host smaller amounts makes things very complicated, but we'll get there.

On the other hand I'll give a preview of a new offer I'm pretty excited about.

Similar to purchasing a cell phone on contract, I want to give miners the opportunity to land a larger amount of hashpower with a smaller amount of up front capital. So for example, you could put down a 30 - 40% deposit on a half rack hosted. This would put your hardware in my datacenter, where it would mine-out the remaining amount owed on the order. Of course you will pay more for the hardware financing it this way and it would require hosting which adds a revenue share (5% - 8%). Once the gear is paid off you could take delivery, or leave it in hosting mode.

I'm working out the details on this, but just wanted to give people a little preview of the idea. I'd love to get your feedback on the idea - good or bad!

Highly interested also. Pending finalization.

Does anyone know how thick the h-boards are? I'm looking at making some mounting brackets for the end with a little tab sticking for screwing the board into a brace.

Thanks,

The fact Dave is happy to tell us about production phases, without even the slightest trace of 'covering my assness' - fills me with confidence - this is the one company that gives me a "good vibe"

Couldn't have said this any better - this really makes me feel good.
